Abstract
Abstract An esophageal probe comprising, a disposable housing comprising an elongated sleeve defining a cavity, and a proximal connector. The probe has a permanent monitoring device comprising an elongated stem receivable in the sleeve cavity with a distal end of the stem located adjacent a distal end of the sleeve when the stem is fully inserted into the sleeve cavity. The monitoring device monitors a body function of a patient from a location adjacent a distal end of the stem, and has a proximal connector. The connector of the monitoring device is releasably attached to the connector of the housing when the stem is fully inserted into the sleeve cavity.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
165 words
An esophageal probe, comprising: a disposable housing comprising an elongated sleeve defining a cavity having a proximal end, a distal end and an inner surface, said housing having a proximal opening communicating with the cavity; a permanent monitoring device having an elongated stem removably receivable through said opening in said sleeve cavity, said stem having a proximal end, a distal end and means for monitoring a body function of a patient from within the sleeve; a pair of spaced electrodes on an outer surface of the sleeve; means for releasably attaching said monitoring device to said housing with said stem received in the sleeve cavity; and means for establishing electrical connection between the electrodes and the probe monitoring device, wherein the electrical establishing means comprises a pair of spaced contacts electrically connected to the electrodes on said inner surface of the sleeve, and a pair of spaced contacts on said stem which contact the sleeve contacts when the monitoring device is attached to the housing.
Claim 2
Dependent Claim
165 words
An esophageal probe, comprising: a disposable housing comprising an elongated sleeve defining a cavity having a proximal end, a distal end and an inner surface, said housing having a proximal opening communicating with the cavity; a permanent monitoring device having an elongated stem removably receivable through said opening in said sleeve cavity, said stem having a proximal end, a distal end and means for monitoring a body function of a patient from within the sleeve; a pair of spaced electrodes on an outer surface of the sleeve; means for releasably attaching said monitoring device to said housing with said stem received in the sleeve cavity; and means for establishing electrical connection between the electrodes and the probe monitoring device, wherein the electrical establishing means comprises a pair of spaced contacts electrically connected to the electrodes on said inner surface of the sleeve, and a pair of spaced contacts on said stem which contact the sleeve contacts when the monitoring device is attached to the housing.
Claim 3
Dependent Claim
14 words
The probe of claim 1 wherein the monitoring means comprises a vibration detection device.
Claim 4
Dependent Claim
13 words
The probe of claim 2 wherein the vibration detection device comprises a microphone.
Claim 5
Dependent Claim
46 words
The probe of claim 2 wherein the distal end of the stem is located adjacent the distal end of the sleeve when the housing is attached to the monitoring device, and in which the vibration detection device is located adjacent the distal end of the stem.
Claim 6
Dependent Claim
12 words
